Embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings, to make those skilled in the art with reference to specification text
Word can be implemented according to this.
As Figure 1-4, the invention provides a kind of hob-type straw chopping cylinder, including:Closed roller 100, its
For hollow cylindrical tube closed at both ends, the barrel of the cylinder and end face are respectively provided with certain thickness, the closed rolling
100 bosom positions of cylinder are provided with the supporting plate parallel with both ends of the surface, and reinforcement and supporting role are played to the roller frame.It is described
The both ends of closed roller 100 are fixedly and coaxially connected hobboing cutter axle 130;Closed roller 100 is divided into multiple construction sections vertically.
In the present embodiment, closed roller 100 is cast iron quality, and barrel lenght is 800~900mm, and external diameter is 600~800mm, described
Construction section is two, respectively the first construction section 110 and the second construction section 120, the first construction section 110 and the second construction section 120
Equal length, and there is fraction to partly overlap region among the first construction section 110 and the second construction section 120.Using closed rolling
Cylinder, can prevent that stalk is involved in inside shredding mechanism in the course of work, cause shredding mechanism to block, and cleaning is difficult.Shredding mechanism
The abrasion of shredder bar can also be aggravated by blocking, it is therefore prevented that shredding mechanism blocks the life-span that can also extend shredder bar.
Multiple hob heads 200, it includes footing 210 and the mounting surface 220 with footing in certain angle of inclination, footing 210
It is integral type structure with mounting surface 220, footing 210 is fixedly connected on the outer wall of closed roller 100 using welding manner.Peace
Angle between the excircle tangential direction of dress face 220 and the closed roller 100 is 20 °~30 °.
Multiple shredder bars 300, it is the flat plate blade of parallelogram, and the shredder bar 300 is detachably arranged in institute
State on hob head 200, the lower surface of shredder bar 300 is resisted against on the mounting surface 220.Preferably, the shredder bar 300 has
There is double-sided blade, respectively on one group of longer opposite side of the shredder bar 300, and the double-sided blade is respectively positioned on shredder bar 300
Upper surface.Two blade surfaces 310 are different according to the direction of installation, respectively as chopping sword and standby sword, used in chopping cylinder
Cheng Zhong, only shred sword and play a part of cutting stalk, use can be exchanged by shredding sword and standby sword, to increase the use of blade
Life-span, while the time of processing blades again is saved, improve operating efficiency.
The size of mounting surface 220 is less than the size of the lower surface of shredder bar 300, width and the table of shredder bar 300 of mounting surface 220
It is of substantially equal that face width removes two width of blade face 310.The middle part of shredder bar 300 is uniformly arranged multiple along edge line direction
Through hole 330, the middle part of mounting surface 220 are provided with and the 320 one-to-one internal thread of through hole along the direction of vertical mounting surface 200
Hole, shredder bar 300 is connected on the mounting surface 220 using bolt 330.After installation, the twolip face of shredder bar 300 is just
Well outside the region of the shredder bar upper surface corresponding to mounting surface 220.The mounting surface 220 of the hob head and the closing
The angle that the excircle tangent line of formula roller 100 is formed is 20 °~30 °, makes the surface of shredder bar 300 and the closed roller 100
Excircle tangent line formed angle δ be 20 °~30 °.When the lower surface of shredder bar 300 is resisted against on the mounting surface 220,
The angle that the excircle tangent line of mounting surface 220 and the closed roller 100 is formed and the surface of shredder bar 300 with it is described closed
The angle δ that the excircle tangent line of roller 100 is formed is equal;It can also be installed between the lower surface of shredder bar 300 and mounting surface 220
Pad, the angle formed to the excircle tangent line of shredder bar 300 and the closed roller 100 is finely adjusted, to reach best
Chopping result.
300 interlaced arranged for interval of shredder bar on first construction section 110 and the second construction section 120, i.e., the first installation
Space in section 110 between two adjacent shredder bars 300 is just relative with the position of the shredder bar 300 on the second construction section 110,
And the angle formed between the edge line of two groups of shredder bars 300 and closed cylinder axis is complementary relationship.That is the first construction section
The angle between edge line and closed cylinder axis on 110 is α1, α1For 5 °~10 °;Blade on second construction section 120
Angle between line and closed cylinder axis is α2, and meet α1+α2=180 °.One group of the shredder bar 300 is compared with short opposite sides
It is parallel with the end face of the closed roller 100, it is small to leave one between the end face of the shorter edge of shredder bar 300 and closed roller
Segment distance, and the distance of the shorter edge of the both sides of every group of shredder bar 300 to the end face is equal.Using edge line and cylinder axis
Between arrangement in a certain angle, the stalk of chopping can be made to be easier to slide from chopping cylinder, avoid shredding
Knife is parallel with cylinder axis and the defects of stalk is easily clipped between along the circumferential direction two adjacent shredder bars;It is simultaneously again unlikely
In causing blade load uneven because angle of inclination is much.
The matrix material of shredder bar blade is 65Mn, and wearing layer prepares and uses laser composite cladding method, melted at blade
Fe55 iron-based material is covered, sword area hardness is HRC50~60, and shredder bar blade sharpening angle beta is 20 °~30 °, blade is had foot
Enough rigidity, wearability is good, and service life is longer.
In summary, hob-type straw chopping cylinder provided by the invention, provided with closed roller and staggeredly interval is tilted
The hobboing cutter of arrangement, the defects of shredding mechanism of existing stalk harvester can be overcome easily to block;Shredder bar is double-sided blade structure,
It can realize that the exchange of work blade surface uses, increase the service life of blade, while save the time of processing blades again, carry
High workload efficiency;Shredder bar cutlery has enough rigidity, and wearability is good, and service life is longer.
Although embodiment of the present invention is disclosed as above, it is not restricted in specification and embodiment listed
With it can be applied to various suitable the field of the invention completely, can be easily for those skilled in the art
Other modification is realized, therefore under the universal limited without departing substantially from claim and equivalency range, it is of the invention and unlimited
In specific details and shown here as the legend with description.
